Quick Facts & SEO‑Rich Snippets
| Métrico | Recomendación | Por que importa |
|---|---|---|
| Max dry ice per air package | 200 kg (Aquí está Pi 954) | Aceptación del transportista |
| Sublimation rate in 30 mm EPS | ≈ 0.45 kg·h⁻¹ | Sizing calculator input |
| Label size | 100 mm Class 9 diamond | Prevents ramp rejection |
| Minimum R‑value | ≥ 4.6 hr·ft²·℉ / BTU | Meets –18 ℃ hold for 48 h |

Dry‑Ice Quantity Calculator (Regla general)
Fórmula:
Hielo seco (kilos) = [Masa de productos (kilos) × 1.1 × Días de tránsito] × 1.15 (amortiguador de seguridad)
Ejemplo:
Shipping 5 kg steak for 48 h ⇒5 × 1.1 × 2 × 1.15 ≈ 12.7 kg dry ice
Resultado: USDA core temp held at –25 ℃ with 8 % reserve.

Step‑by‑Step HowTo: Packing with Dry Ice
-
Precongelación product to –20 ℃ for ≥ 24 h.
-
PPE on: cryo‑gloves, gafas de protección, apron.
-
Pesar & registro masa de hielo seco; log electronically.
-
Aislamiento de capas: double‑wall carton → 30 mm EPS → product center.
-
Hielo seco de carga superior blocks on all six sides; wrap in kraft to slow burn‑off.
-
Respiradero & sello: leave 6 mm holes; tape flaps, not vents.
-
Etiqueta: "Y 1845, Dióxido de carbono, Sólido, Net __ kg” + Diamante de clase9.
-
Documento: Tick “Dry Ice” on airwaybill—no DG declaration for non‑haz goods.

Costo & Carbon Optimisation
| Táctica | % Cost Saved | Notas |
|---|---|---|
| Rightsize cartons | 6–8% | Less void = slower sublimation |
| AI lane modelling | 10–15 % | Predicts weather‑driven ice needs |
| 70 % dry ice + PCM blend | 12–18% | Avoids hazmat fees on last mile |
| DAC‑sourced dry ice credit | Up to $30 / t CO₂ | EU ETS eligibility |
Hielo seco vs. –22 ℃ PCM Bricks
| Métrico | Hielo seco (–78 ℃) | PCM Brick (–22 ℃) |
|---|---|---|
| HazMat paperwork | Requerido | Ninguno |
| 48 h hold weight | 12 lb | 8 lb |
| Reutilizabilidad | De uso único | 30 + ciclos |
| Mejor para | Helado, biológicos | Comidas congeladas, meat kits |
Consejo:
Blend 30 % PCM to cover delivery‑day delays without leftover dry ice for customers to dispose of.

Preguntas frecuentes
¿Necesito una declaración de materiales peligrosos para el hielo seco??
Respuesta:
No, if dry ice is used to cool bienes no expertos. You only need to etiquetar el paquete y note the net weight — no declaration is required.
How long does 5 lb dry ice last?
Respuesta:
Aproximadamente 30–36 horas en 30 mm EPS container en 21 ℃ ambient temperature.
Consejo: Agregar un 20 % buffer for unexpected delays.
¿Puedo cambiarme a PCM para evitar cargos por materiales peligrosos??
Respuesta:
Sí - PCM bricks at –22 ℃ are effective for goods that can tolerate –15 ℃.
Siempre verify lane performance before switching.
Safe disposal advice for customers?
Respuesta:
dejar hielo seco sublimate outdoors in a well-ventilated area.
Never dispose in fregaderos o closed rooms.
Mantener lejos de niños y mascotas.
